ABSTRACT:
A method of removing electrical terminals (14) having a compressible compliant section (16) disposed within a circuit board through-hole (46) in an interference fit, the terminal insertion end (18) projecting from the through-hole (46) and beyond a remote surface (44) thereof when fully inserted. The method includes the steps of: providing a tool (50)having a work surface (54) including an array of work sites (56), each associated with a terminal (14); urging the work surface (54) of the tool (50) against the remote side (44) of the board (40) and performing a work step on the insertion end (18) to at least temporarily alter the insertion end at the through-hole exit thereby reducing the retention force; and pulling the terminal (14) from the through-hole from the insertion side (42) of the board. In one embodiment an aperture (56) in the tool (50) is dimensioned to receive the insertion end and the alternation step includes compressing the outwardly extending portion of the compliant section. In another embodiment the alteration step severs the insertion end of the terminal.
